Salvia mexicana: The Towering Mexican Sage

The Majestic Blue Sage

Salvia mexicana, the Mexican Sage, is a statuesque perennial native to Mexico and Central America. Its towering stature and intense blue flowers make it a dramatic back-of-border presence in frost-free gardens.

Botanical Profile

Statuesque Blue Spikes

This robust perennial grows 5-10 feet tall and 3-6 feet wide with square stems and large, ovate, textured leaves. In late summer to fall, it produces impressive terminal spikes 12-24 inches long of intense, deep blue flowers with contrasting green calyces. The combination of blue flowers and green calyces is distinctive and beautiful.

Mexican Sage thrives in full sun to partial shade with rich, well-draining soil and regular moisture. It's a substantial plant that needs space. Hardy in zones 8-10; in colder zones, grow as an annual or in a conservatory. Cut back hard in late winter.

Architectural Back-of-Border Plant

Use at the back of deep borders, as a specimen, or in large containers where its height commands attention. The late-season blue blooms extend the garden's color into fall. Attracts hummingbirds, bees, and butterflies. Combine with fall-blooming composites (asters, mums) and ornamental grasses. A bold, structural salvia for large spaces.
